Technical Field
[0001] This application relates to the field of wheel speed sensors, and more particularly to an injection-molded high-strength wheel speed sensor connector. Background Technology
[0002] Wheel speed sensors are used to measure the rotational speed of a car's wheels. Commonly used wheel speed sensors include magnetoelectric wheel speed sensors and Hall effect wheel speed sensors. Wheel speed information is essential for modern vehicles. Vehicle Dynamics Control (VDC), Electronic Stability Program (ESP), Anti-lock Braking System (ABS), and automatic transmission control systems all require wheel speed information, making wheel speed sensors one of the most critical sensors in modern automobiles.
[0003] Most wheel speed sensor connectors currently in use are connected by direct plug-in. During connection, no sealing device is installed at the connection between the connector and the plug, which results in poor sealing at the connection. On complex road surfaces or roads with a lot of water, water may enter from the connection and enter the interior of the connector, affecting the use of the wheel speed sensor. Utility Model Content
[0004] To address the issue that the lack of a sealing device at the connection point of the connector and plug leads to insufficient sealing, which may cause water to enter the connector from the connection point on complex road surfaces or roads with a lot of water, this application provides an injection-molded high-strength wheel speed sensor connector.
[0005] The injection-molded high-strength wheel speed sensor connector provided in this application adopts the following technical solution:
[0006] The device includes a handle and a connecting cable. One end of the handle is fitted with a protective shell, and a connector is located inside the protective shell at one end of the handle. A movable sleeve is movably mounted on the outer side of the protective shell, and a sealing ring is installed on the inner side of the movable sleeve, with one end of the sealing ring extending beyond the inner side of the movable sleeve.
[0007] By adopting the above technical solution, the first anti-slip strip set on the side can avoid the difficulty of applying force when plugging in, so that the plug can be plugged in. After the plugging is completed, it is protected by the protective shell on the outside of the plug.
[0008] Preferably, the protective shell has movable grooves on both outer sides, and two limiting slots are provided inside the movable grooves on the protective shell.
[0009] By adopting the above technical solution, the first circular locking post and the second circular locking post enter the interior of the limiting locking groove, and the moving sleeve is restricted and fixed through the interior of the limiting locking groove, thereby improving the overall stability.
[0010] Preferably, a central shaft is installed inside the movable sleeve, and a first movable component and a second movable component are installed on the central shaft.
[0011] By adopting the above technical solution, the force of the inner spring facilitates the expansion of the first and second elastic plates outward around the central axis, which makes it easier to fix the movable sleeve later.
[0012] Preferably, a first elastic plate is installed on the first movable component, and a first circular locking post is installed at one end of the first elastic plate; a second elastic plate is installed on the second movable component, and a second circular locking post is installed at one end of the second elastic plate; the first elastic plate and the second elastic plate are located inside the moving groove.
[0013] By adopting the above technical solution, when the first movable member and the second movable member move, the first elastic plate and the second elastic plate move, and the first elastic plate and the second elastic plate drive the first circular locking post and the second circular locking post to move along the inner wall of the moving groove.
[0014] Preferably, the two limiting slots are semi-circular, and the size of the limiting slots is adapted to half the size of the first circular locking post and the second circular locking post. The outer sides of the first circular locking post and the second circular locking post can be located inside the limiting slots.
[0015] By adopting the above technical solution, the first circular locking post and the second circular locking post enter the interior of the limiting locking groove, and the moving sleeve is restricted and fixed through the interior of the limiting locking groove.
[0016] Preferably, the first elastic plate and the second elastic plate are arranged opposite to each other, and a spring is provided between the first elastic plate and the second elastic plate, with the two ends of the spring connected to the inner sides of the first elastic plate and the second elastic plate, respectively.
[0017] By adopting the above technical solution, the force of the inner spring can extend the first elastic plate and the second elastic plate outward around the central axis.
[0018] Preferably, the handle is provided with a first anti-slip strip on both sides, and the movable sleeve is provided with a second anti-slip strip on both sides.
[0019] By adopting the above technical solution, the first anti-slip strip set on the side can avoid the difficulty of applying force during insertion.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. In this application, the first and second elastic plates drive the first and second circular locking pins to move along the inner wall of the moving groove. When the first and second circular locking pins move to positions corresponding to the two limiting locking grooves, the force of the inner spring can expand the first and second elastic plates outward around the central axis. At this time, the first and second circular locking pins enter the interior of the limiting locking grooves, and the moving sleeve is restricted and fixed by the interior of the limiting locking grooves. At this time, one end of the sealing ring on the inner side of the moving sleeve is attached to the outer surface of the insertion part to seal the connection and improve the tightness of the connection.
[0022] 2. This application allows the user to grip the handle and use the first anti-slip strip on the side to avoid difficulty in applying force during insertion, thus enabling the connector to be inserted. After insertion, the connector is protected by the outer protective shell, improving the overall protective performance. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.
[0031] This application discloses an injection-molded high-strength wheel speed sensor connector. Please refer to... Figure 1 and Figure 2 The device includes a handle 1 and a connecting cable 2. One end of the handle 1 is equipped with a protective shell 3. A connector 4 is inserted into the handle 1. After insertion, the connector 4 is protected by the protective shell 3. One end of the handle 1 is located inside the protective shell 3 and has a connector 4. A movable sleeve 6 is movably installed on the outside of the protective shell 3. A sealing ring 7 is installed on the inside of the movable sleeve 6. One end of the sealing ring 7 extends beyond the inside of the movable sleeve 6. First anti-slip strips 5 are provided on both sides of the handle 1. Second anti-slip strips 18 are provided on both sides of the movable sleeve 6. Movable grooves 8 are provided on both sides of the outside of the protective shell 3. Two limiting slots 9 are provided inside the movable grooves 8 on the protective shell 3. The first anti-slip strips 5 on the side can prevent difficulty in applying force during insertion.
[0032] Please refer to Figures 3 to 6 The movable sleeve 6 has a central shaft 10 installed inside. A first movable part 11 and a second movable part 13 are mounted on the central shaft 10. A first elastic plate 12 is mounted on the first movable part 11, and a first circular locking post 15 is mounted at one end of the first elastic plate 12. A second elastic plate 14 is mounted on the second movable part 13, and a second circular locking post 16 is mounted at one end of the second elastic plate 14. The first elastic plate 12 and the second elastic plate 14 are located inside the movable groove 8. Two limiting grooves 9 are semi-circular, and the size of the limiting grooves 9 is half the size of the first circular locking post 15 and the second circular locking post 16. When the small phase is adapted, the movable sleeve 6 is pushed forward. The movable sleeve 6 moves forward gradually, which drives the central shaft 10 to move. When the central shaft 10 moves, it can drive the first movable part 11 and the second movable part 13 to move synchronously inside the movable groove 8. When the first movable part 11 and the second movable part 13 are passed, the first elastic plate 12 and the second elastic plate 14 move. The first elastic plate 12 and the second elastic plate 14 drive the first circular locking post 15 and the second circular locking post 16 to move along the inner wall of the movable groove 8, which can facilitate the first circular locking post 15 and the second circular locking post 16 to enter the interior of the limiting locking groove 9.
[0033] Please refer to Figures 4 to 6The outer sides of the first circular locking post 15 and the second circular locking post 16 can be located inside the limiting groove 9. The first elastic plate 12 and the second elastic plate 14 are arranged opposite to each other, and a spring 17 is provided between the first elastic plate 12 and the second elastic plate 14. The two ends of the spring 17 are respectively connected to the inner sides of the first elastic plate 12 and the second elastic plate 14. Through the force of the inner spring 17, the first elastic plate 12 and the second elastic plate 14 can be extended outward with the central axis 10 as the center. At this time, the first circular locking post 15 and the second circular locking post 16 enter the interior of the limiting groove 9. The movable sleeve 6 is restricted and fixed through the interior of the limiting groove 9. At this time, one end of the sealing ring 7 on the inner side of the movable sleeve 6 is attached to the outer surface of the insertion part to seal the connection.
[0034] The implementation principle of the injection-molded high-strength wheel speed sensor connector in this application embodiment is as follows: During use, the hand grips the handle 1, and the first anti-slip strip 5 on the side prevents difficulty in applying force during insertion. The connector 4 is then inserted. After insertion, the connector 4 is protected by the outer protective shell 3. Then, the moving sleeve 6 is pushed forward, gradually moving forward. The moving sleeve 6 drives the central shaft 10 to move. When the central shaft 10 moves, it drives the first movable part 11 and the second movable part 13 to move synchronously inside the moving groove 8. Through the first movable part 11 and the second movable part 13, the first elastic plate 12 and the second elastic plate 14 move. The elastic plate 12 and the second elastic plate 14 drive the first circular locking post 15 and the second circular locking post 16 to move along the inner wall of the moving groove 8. When the first circular locking post 15 and the second circular locking post 16 move to the position corresponding to the two limiting locking grooves 9, the force of the inner spring 17 can expand the first elastic plate 12 and the second elastic plate 14 outward with the central axis 10 as the center. At this time, the first circular locking post 15 and the second circular locking post 16 enter the interior of the limiting locking groove 9 and restrict and fix the moving sleeve 6 through the interior of the limiting locking groove 9. At this time, one end of the sealing ring 7 on the inner side of the moving sleeve 6 is attached to the outer surface of the insertion part to seal the connection.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
